Smartcard Extension 1.3.6.1.4.1.311.25.2 support

[alfonsrv]

See pyca/cryptography#10370 – would be great if the extension would be displayed / loaded into Django CA properly once it's available

Hi @alfonsrv,

Thanks for the report!

This sounds good, I usually integrate extensions once they become available. I will link the commits here when integrating support for the first cryptography release that supports it.
